Abstract

The invention discloses an energy-saving thermal insulation material for building walls and a preparation method thereof. The energy-saving thermal insulation material comprises 15-30 parts of polystyrene, 5-15 parts of glass wool, 4-10 parts of rape stalk, 3-7 parts of cassava stalk, 6-14 parts of phenolic foam, 3-8 parts of magnesium chloride, 4-7 parts of poly(chlorotrifluoroethylene), 3-6 parts of calcium fluoride and 4-9 parts of diatom ooze. The preparation method comprises the steps of crushing, stirring for mixing, die forming, cooling and the like. The prepared energy-saving thermal insulation material has the characteristics of high rupture strength, low heat conductivity and high oxygen index.

Description

technical field [0001] The invention belongs to the field of novel composite materials, and relates to an energy-saving heat-preservation material for building walls and a preparation method thereof. Background technique [0002] Building energy-saving materials refer to building materials that maintain low energy consumption in the daily use of buildings, and achieve the purpose of building energy conservation by changing the characteristics of the materials themselves. Energy-saving materials belong to thermal insulation materials; thermal insulation materials refer to materials or material composites used for building envelope or thermal equipment and resisting heat flow transfer, including both thermal insulation materials and cold insulation materials. [0003] Organic energy-saving thermal insulation materials include straw, rice husk, sugarcane fiber, cork kapok, wood chips, shavings, wood fiber and their products. Such materials have small bulk density, wide sources...
